Website design usability improvements can double sales and visitor satisfaction, and site visitor satisfaction means extra return visits. A company’s website is many times the first experience with that company so usability and a quality user experience is critically important to a company’s online Internet success.
Typical websites have usability issues which put off potential clients leaving them with confusion and frustration. This can all be corrected. This how-to guide is intended for a new website, or those that have a website that doesn’t perform to their expectations.
Usability – The Numbers
- Forrester Research studies estimate that 50 percent of potential sales are lost because visitors can’t find sought after information and 40 percent of visitors do not return to a site after a negative first experience.
- According to Jakob Nielsen usability expert, web site re-design based on usability standards can increase online sales by 100%
- Usability projects can return 5-10 times their expense within 12 months.
- A comprehensive usability project can improve website results by 83%. Since competitors will probably incorporate some of the changes you implemented, this can settle out to 68%.
Page Layout And Structure Usability
- Web design quality increases credibility – just do it
- Error free HTML (or XHTML) and CSS ensures uniform cross-browser page rendering. A discombobulated web page will kill your credibility.
- Whitespace usage increases comprehension by 20%
- Golden Triangle is important. That is the top-left of the page above the fold (before scrolling). Jakob Nielsen’s user scrolling study showed that 23% of visitors scroll on their first website visit.
- Faces not looking at you – if a face image is looking somewhere other than directly at us, we’ll also look in the same direction. Take advantage of this by drawing your users’ attention to the most important parts of your page or ad.
- Search box size counts – a 27 character search box shows all search text in 90% of searches according to Jakob Neilsen
- Header and footer should be separated from the main content.
Usability and Website Navigation
- Consistent Navigation – make sure navigation appears in the same location on web pages
- Text is king – use descriptive text in navigation links, not images, java applets or flash
- Location feedback – provide the user with information about where they are with colors, breadcrumbs or hyperlink styles
- Sitemaps – provide a visitor sitemap with a website outline and your most important links
- Calls to action or navigation boxes can’t look like ads because users automatically skip over them
- Home page navigation placed on the top of pages performs best
Usability and Text Characteristics
- Dominant headlines will draw the visitors eye immediately
- Headlines first words must grab your visitors attention immediately. If they are keywords then you also get an SEO benefit out of it.
- Headings, subheads, date/times and phone numbers should be used and formatted consistently. Using a logical progression of h1, h2, h3, etc. tags helps the web site visitors understanding of the page hierarchy and is also a great accessibility feature.
- Standard fonts of 12 points or more optimize reading speeds
- A white background with black text increases reading speeds up to 32%
- Sentence case (only first word capitalized) is important for comprehension and reading speed
- Bold and italics should be used sparingly, and ideally only to emphasize keywords ultra-relevant to the topic
Link Definition Usability
- Blue anchor links are the standard color for links
- Underline links – this is also standard and good for accessibility reasons
- Visited links should be a different, more pale color
- Text link hover color should light up the link with brighter colors
- Red or green links should be avoided due to the number of people that are color blind
- Do not underline any text that is not a link
- Do not show normal text in text link colors
- Do not use bolding as a hover effect. Bolding text will cause the text to re-align.
- Link title attributes can be used for the hover effect to describe where the link is going – also a great accessibility feature
- Link text should describe the target page
- Tabindex is a great method to define logical tabbing through elements
- Menu links should usually not follow the above rules
Usability and Writing Standards
- Write to be scanned – web site visitors don’t read long paragraphs. Keep paragraphs to 3 sentences, group logically and provide succinct information.
- Bullet points should be used as much as possible
- Bold and italics should be used for your most important words. This is also a big SEO factor – search engines rank your page higher when you emphasize targeted keywords.
